A man complains that his sons do not perform the regular voluntary prayers (rawatib), especially the witr prayer; what is the guidance?

Question:
He says: Honorable Shaykh, may Allah grant you success. I have two sons, one is sixteen years old and the other is thirteen. And there is a third. Thirteen years old. No, the other way around. Thirteen years old. Yes, yes. They exhaust me with their standing for the Fajr prayer until the opening takbir is missed, and they also deliberately leave off the witr sunnah and the Fajr sunnah. The older one says to me that they are not obligatory, so they do not bind us. The question is: should I leave them to pray it or not pray it? Or what should I do? May Allah preserve you.

Answer:
The obligatory prayer is the important one; the obligatory prayer must not be missed by them. The obligatory prayer is the most binding and most important thing. As for the rawatib, if they perform them, it is an increase in good, and if they do not perform them, they are not obligated to do so. But you must be patient with them and wake them up early so that they can perform the Fajr rawatib and catch the congregation. Yes.
